Dear SAMANTHA DREW,
I cannot say how much I appreciate the loan of your laptop last week. It was a shock when my machine broke and know that without your help I would never have got the work finished on time. You did not have to loan me your laptop and it was a generous act to do so.
Whenever you need any help please do not hesitate to give me a call.
